tuals—until now. For the past decade or so, we have had the computational
power to run mapping software on desktop PCs, and a number of compa-
nies have provided us with digital atlases with extensive street maps. In the
mid-1990s, MapQuest exploded onto the scene, forever changing the way
people send out party directions. None of this software, however, really
allowed people to personalize their maps. That continued to be a feature of
software that cost thousands, if not tens of thousands, of dollars. Only
recently has lower-priced, consumer-grade mapmaking software become
commonplace, and it still isn’t as easy to use as your average Microsoft or
Adobe product. However, for über-hackers like us, it’s ready for prime time!
Preparation
This hack gets us started with mapmaking in Java by installing an open
